Grandstream GXW4248 48 Ports FXS Analog PBX VoIP Gateway

The Grandstream GXW4248 is a VoIP gateway that provides 48 FXS ports, letting you keep familiar analog phones and fax machines while moving your voice traffic to an IP network. It bridges legacy equipment with SIP-based systems, so you can upgrade your communications without replacing every handset on the premises.

Because the gateway follows open SIP standards, it pairs smoothly with most IP PBXs, hosted VoIP services, and softswitch platforms. Gigabit Ethernet connectivity helps maintain clear call quality even when network traffic is busy, and built-in security features guard every conversation against unwanted access. Dial plans are flexible, allowing you to mirror existing extension patterns or create new ones that fit your workflow. A front-panel display supports multiple languages, making on-site setup quick for administrators and technicians.

The GXW4248 fits naturally in places that still rely on a high count of analog endpoints. Hotels can keep guest room phones online while the back-office moves to IP. Schools, hospitals, and manufacturing plants can link emergency phones, paging systems, or fax lines to the same network used for newer VoIP handsets. Call centers with analog agent sets can transition at their own pace without service interruptions.

Installation is straightforward. The unit slides into a standard rack, and web-based provisioning tools simplify large rollouts or remote management. Whether you are expanding an existing analog PBX, consolidating voice infrastructure at a branch office, or planning a phased migration to IP, the Grandstream GXW4248 delivers reliable, high-density FXS capacity in one tidy package.
